Wijzigingsstromen

Wijzigingsstromen, often translated as change streams or change data capture (CDC) streams, are a mechanism for tracking and propagating changes made to a database. Instead of querying the database directly for modifications, wijzigingsstromen capture these changes in near real-time as they occur. This typically involves monitoring the database's transaction log, which records every alteration.

When a change is committed to the database, it's also written to the transaction log. Wijzigingsstromen systems read this log and transform the raw log entries into a more usable format, such as a stream of events. Each event represents a specific operation, like an insert, update, or delete, along with the relevant data associated with that change.

The primary benefit of wijzigingsstromen is enabling efficient and low-latency data synchronization. Applications can subscribe to these streams and react immediately to database modifications. This is crucial for various use cases, including building real-time dashboards, replicating data to other systems, feeding data warehouses, implementing microservices architectures, and performing audits. By decoupling the change detection from the applications that consume the changes, wijzigingsstromen reduce the load on the primary database and improve overall system responsiveness.
